Refurbishing my trek 4100

Posts: 15
Hi guys,
Looking for a little help.
I am refurbing my Trek 4100 thats been outside for a few years.
I know i need new forks, chain, bars, and saddle.
What i need help with is what forks will fit, im afraid im not very up on bikes and am unsure of the sizes!
I am looking for some sub £100 forks for cross country riding, the rest of the bike is still standard, any suggestions?
may streach a little further but everything will prob come from e-bay.
many thanks

Need to know what year the bike is really and a list of existing parts. Photo would be good too.0

Umm dont have recipt but Post modern Fork manual was printed in 99.
The frame is black with red text.
Running gear is shimano acera/altus.
forks are awful post modern SE's.0 -
The forks are liable to have a threaded steerer, probably of the 1inch variety, rather than the normal 'standard' of 1.1/8th inch and threadless. This will make finding a fork that fits pretty hard!
However, I have found this:

Is that your bike? I cant tell from the pic how the fork fits.0 -
similar but not the disc model.
is there a way i can check the fitting? i have all the tools here and the bike next to me. do i just undo the alan bolt at the top?
sorry for being a little basic0 -
Does the stem sort of fit inside the fork steerer, as opposed to clamping around it? (stem being the bit that holds the bars)0
-
ok just had forks off.
it clamps around the fork tube, with a separate cap that sits above the stem which has a bolt threw it down into a thread into the top of the fork tube. but stem deff fits over fork tube.0 -
also fork tube has an O/D of 1.1/8 inch0
-
Excellent, this opens a lot of options up! The top bolt is used to adjust the bearings, when the stem bolts are undone (it pulls the whole lot onto the headset)
For a 100 quid I'd look at the Rockshox Tora 302 - not the lightest, but 10 times the fork you have with proper hydraulic damping and lockout. Also much stiffer as well.
As for chain, somethng from SRAM like the PC48 would be my recommendation - however you will probably need to change the cassette and maybe chainrings too.
Bars, well depends on budget ans style, but yours will be the 25.4mm standard fitting. easton EA30 or EA50 worth looking at.
Saddles are a personal thing, but many like the new Charge Spoon. It will fit no probs on your existing seatpost, as will most saddles.0 -
excellent i will go a hunting now0
-
are these suitable for my v braves still?0
-
Looks like this will not take my v brakes? any other suggestions?0
-
The Tora is available with V mounts, or disc only.0
-
looking past forks, if i was to up the budget to get new forks, disc brakes and wheels, what would be a reasonable figure/spec? id rather spends and build up good parts, and change frames later if i choose, than buy a bike for 400 quid with cheap parts.0
-
100 quid for forks minimum, 100 for discs, 100 for wheels. Maybe need new shifters (if they are integrated to your existing brake levers). Also, is your frame disc ready ie has the mounts to fit them?
Some 500 quid bikes are equipped with RS Toras, twin piston hydro brakes, decent wheels, 27 gears, fully butted frames. Mybe worth considering selling what you have and adding it to the budget.
For 600 have the Rockhopper disc.0 -
Hey sorry for deleayed reply. how do i know if my frame has disc mounts?
i now have a full Scott Tampico 7005 i can use/strip.
frame is almost identical to the treck i notice. (are the old rockshox indy s forks any good?)0 -
The mounts willl be located on the left hand rear dropout - google for disc mounts to see images.
Indy is a very old fork, stopped in 1998. Light, but undaamped, short travel and very flexy.0 -
cool, well i have stripped and built the scott, my it is a light frame.
All parts are good, only thing i will be doing is the shocks for now.
Deore v brakes are a lot better then the ones on my treck. And my bro has recently added a good rear cassette.
So if i can budget £180 for forks whats the best i can get. The rockshox range looks good, or the marzocchi range.
Also getting a charge spoon.
where do you guys order from usually?0 -
Spend an extra 20 and you can get an RS Reba from Merlin - great fork for that money, over a pound lighter than the MX pro and much more adjustable.0
